I wish I could do phone calls and text messages using a 8" tablet, but that functionality is not offered — directly. It is possible to do those things on a tablet but only if you first tether the tablet to a smartphone over WiFi, even if the tablet has cellular connectivity. This seems like a useless artificial limitation to me. Why not give users the choice if they want it?
